Primary sources & references
The works that organize this site, the repositories used to check them, and the rules followed when a passage becomes an article.

Digital witnesses used for the first article
The first Bansenshūkai article checks the work’s identity and structure against the National Archives of Japan digital record. That record identifies Fujibayashi Yasutake, describes a manuscript in twenty-two volumes plus one military-secret volume, and releases its images under CC0.
The normalized text and page-level identification are checked against Iga City’s Digital Museum transcription. The placement of “Seishin” in the table of contents is cross-checked with the Iga-ryu Ninja Museum database.
Citation policy
Each reading article names the work and a locatable division such as volume, chapter, section, or entry. Short original-language quotations appear apart from the site’s newly written translation. The explanation distinguishes the wording of the passage from contextual inference.
If manuscript or editorial numbering differs, the article identifies the digital witness used rather than silently forcing one numbering system onto all copies. The internal excerpt ledger tracks cumulative use and closes a source to new excerpts at an estimated eight percent.
Images
Any image used on this site must be demonstrably public domain or offered under a compatible reuse license, and every image carries a visible source and rights caption.
